Sensor.py Remote I/O Error from Dust Sensor (Sharp GP2Y10 14 7218)

Opening the next issue, when calling Sensly.py It crashes on a readbyte, already tried to reset the GPIO before but does not solve the problem.

@samAlti What did you modify into the base Adafruit BME280 driver? do you remember? comparing them is too difficult there were too many changes. My idea is to use the Adafruit one, it seems you only use the read_temperature & read_humidity into it. What do you say?

For the moment its crashing into the init sometimes & read_temperature for sure (from your bme_combo.py file)

Increased counter between write & readbyte on dust sensor, but getting 15, 255 as data always, the produced results after your calculations seem false...

seems that this person has same problem... https://forum.dexterindustries.com/t/interacting-with-a-sharp-gp2y1010-dust-sensor/1878

I/O Error disappeared so closing the issue, even if I don't know if the data are correct...

@phgachoud thank for your update
I'll try to keep up with the modifications, where i can pull the new files I'll do some testing and if i can contribute I'll try to

Thanks
BTW my update.sh never worked
